I have tested a slide projector condenser lens with a torch and can see a cone of light produced by the lens. This cone is in focus on the subject. Would the size of the patch stop match this cone somewhere between the lens and the subject? Would the appropriate field of view of the camera lens then...

I have the Mitty very close to the Raynox as worked out by Nathan so no space for a baffle there. I am talking about the tube between the camera and the back of the Raynox. I am using Fusion 360 to do the design and it can "loft" between a circle and a rectangle a certain distance away and insert ba...

Agree about the water cooling. My CPU has one and it is really neat and compact compared to the huge cooling fan towers that I used to use. I'm thinking about using something like a Corsair Hydro Series H45 for a 39V COB LED if the smallish copper/ally heat sink with fan doesn't do the job. I'm alwa...

I've already bought a 6V, 12V and 24V power supplies and now need to be able to drive a 39V 2.8A LED and have burnt out one of the Luxdrives so wanted to have more control with readouts as to what is going on. Also bought 4 LED cheapo drivers from China with readouts but these induce LED flicker on ...

At the moment I use a DC unit connected to this http://www.luxdrive.com/products/flexblock-a011/
